A nondenaturing zwitterionic detergent for solubilizing membrane proteins and breaking protein-protein interactions. Combines the useful properties of both the sulfobetaine-type and the bile salt detergents. Commonly used for protein solubilization in isoelectric focusing and two-dimensional electrophoresis especially for non-denaturing (without urea) isoelectric focusing.

Sodium dodecyl sulfate (SDS or NaDS), sodiumlaurilsulfate or sodium laurel sulfate (SLS) is an organic compound with the formula CH3(CH2)11OSO3Na. It is an anionic surfactant used in many cleaning and hygiene products.

Dithiothreitol (DTT), also known as Cleland's reagent, is a small-molecule redox reagent. Its oxidized form is a disulfide-bonded 6-membered ring. DTT has an epimeric ('sister') compound, dithioerythritol (DTE).

TCEP. HCl has the advantages of being odorless, a more powerful reducing agent, an irreversible reducing agent, more hydrophilic, and more resistant to oxidation in air. Near complete reduction of disulfide bonds. DTT is a protective agent for reducing –S-S TO SH groups. Used as a strong reducing agent for proteins and enzymes.
